ARCH P. RIDENOUR, F LOS ANGELES, CALIFORNIA BATTERY TERMINAL AND LINER FULLER Application filed June 20, 1928. Serial No. 286,828.

This invention relates to pulling devices of the type employed for pulling wheels from their associated shafts and liners from the structure in which they are mounted, and

has for an object the provision of an improved type of puller provided with means 7 operable to clamp gripping jaws rigidly onto structure, to insure the firm gripping of the article during the pulling process.

The embodiment herein described finds a particular field of utility in pulling-terminal clamps of storage batteries from their associated terminal posts, since this embodiment is relatively small and adapted for doing relatively light work only. I wish it to be understood, however, that the invention contemplates producing the device in enlarged formcomposed of heavier members so that heavier work can be accomplished thereby. Accordingly, in the following description of the device it should be understood that the word terminal is used in a descriptive and not a limiting sense, as the invention may be employed for pulling other devices than bat- V tery terminal clamps.

A more detailed object is the provision of a battery terminal clamp puller wherein the gripping jaws are pivotally mounted upon 0 the frame of the puller and wherein means are provided for mechanically forcing the gripping jaws to gripping position, this means comprising the conical surface of an operating head which isthreaded in to the frame of .the puller with the jaws operatively' engaged with the conical surface in such a manner that as the head is advanced by means of its threaded connection in respect to the frame, the jaws are positively forced to'gripping position.

It is a further object of the invention to providea device of this general character which will be relatively simple and inexpensive in construotionand which will be '4 generally superior-in efficiency and serviceability.- The invention possesses other objects and featurefsof advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the draw ings accompanyingand forming a part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I-may adopt variations of thepreferred form vof my invention as set forth in the claims. the article to be removed from its supporting Referring to the drawings, I

Fig. 5 is a horizontal sectional view, the plane of section being indicated by theline 55 of Figure 1 and the direction of View indicated by the arrows;

In terms of broad inclusion, the pulling device of my invention comprises a frame having a pulling shaft threaded therethrough and a jaw operating head threaded thereupon. A' pair of jaws are pivoted to the frame in'such position that they are in operative engagement with a conical surface which is provided upon said operating head whereby the jaws may be positively moved to gripping position and there retained by moving the operating head in respect to the frame. F Y Specifically describing the present embodiment, my invention comprises a frame composed of a pair of spaced'parallel arms 6 and 7. An operating head 8 has a cylindrical extension 9 provided with threads 11 by means of which a threaded engagement between the operating head 8 and the upper arm 6 is .established,f'it being understood that the portion 9 of the head 8 is threaded through the upperarm'6 midway between the ends thereof. s i

The head 8 is providedwith an axial bore 12 Within which a push'rod 13 isjournaled dj nt its upper end l t, The o her end of the push rod 13 is provided with threads 16 by means of which a threaded engagement with the lower arm 7 of the frame is established. A pushing head 17 is swiveled to the lower end of the push rod 13.

A pair of levers 18 are provided, each being pivoted Joy a pin 19 to one end of the lower'ar n f7 and each having a guide pin 21 rigid therewith adjacent its upper end. The pins 21 are slidable radially in respect to the push rod 13 in slots 22 inthe upper arm 6. Thus, means are provided which substantially prevent relative movement between the upper and lower arms 6 and 7 but which permit levers 18 to swing about their pivots 19 to vary the distance between the upper ends of the lever The lower .ends of the levers 18 are bent inwards to provide gripping jaws -'.3 which, in 1 the present embodiment, are provided with concave ancuate surfaces Qeat their extremities correspo iding radius to the icon-ventional terminal posts 26 ofstorage batteries 2? so that the 23 maybe positioned about one of these posts and engaged beneath the associated terminal e-lamp 28.

Means for mechanically forcing the jaws 23 to gripping pesitien are p ovided. The operating head 8 has a k ur ed flange 31 and a cenical surface .32 flar ngdownwards therefrom. The upper end of e ch of the levers 18 is bent inwards as at. 33 to engage the conical surface 32 so that asthe operating head is threaded upwards the upper arm 6 to which it is threaded, the conical surface 32 will wedge theupper est-1533 of the levers 18 apart. This results moving the levers 18 about their respective pivots 1 9 forcing the gripping jaws 23 inwards.

A leaf spring 36 is attached to the lower arm 7 adjacent each of its ends and ext nds downwards therefrom to engage the adjacent lever 18 below its pivotlt). As result the j aws 23 are normally urged outwards, retaining the upper ends of the levers 18 against the conical surface'32.

The manner of operating my improved.

' puller is substantially as follows:

The operating head 8 is first threaded downwards into the arm 6 to permit the upper en ds 33 of the levers 18 to move together and sepa- "*IfltQ the jaws 2:3 suiiiciently to permit placing the aws 23 under the terminal clamp 28 and upon opposite sides of the terminal post 26 of the battery 27 from which it is desired to remove the terminal clamp 28. Then by rotating the head 8 in that direction which will cause the, head .8 to move upwards from the arm 6, the conical surface :32 may be made to wedge the upper endsSB of the levers 18 apart and force the gripping aws 23 toward each other so to establish a firm grip below the terminal clamp 28. Then thepush rod 13 should be rotated so that its threads 16 cause the push rod 13 to be advanced downwards 1,7eaeee through the arms 6 and 7 constituting the frame of tie device. in order to facilitate such rotation of the push rod 13 a handle 37 is provided at the upper end of the push rod. This rotation of the push rod 13 should be continued until the pushing head 17 rests upon the top of the terminal 26. After this, further rotation of the push rod 13 will result in pulling the terminal clamp 28 from its terminal ost 26.
